The Global South produces almost 80% of eggs globally. Yet, before 2020, only 24% of cage-free commitments were in the Global South, but after 2020, this jumped to 51%. AWF's grants helped kickstart and scale groups across Brazil, Peru, Ghana, Indonesia, Colombia and other countries, securing commitments and ensuring implementation. For example, Sinergia Animal secured over 170 commitments in Latin America and Asia, while Fórum Animal drove accountability by securing progress reports from 30 Brazilian companies. Thanks to all the groups AWF supported, millions of hens escaped confinement.

Malaria is the leading cause of death for children under five. The Malaria Consortium distributes preventive seasonal malaria chemoprevention (SMC) drugs during the high malaria season to hundreds of thousands of children in several countries who would not otherwise receive this life-saving treatment. GiveWell estimates that the Malaria Consortium’s work is eight times as cost-effective as unconditional cash transfers. There is strong evidence that SMC reduces malaria and likely provides additional benefits, such as later-life income.

Researcher Logan Smith has consistently identified and evaluated new methods for interpreting LM activations using Sparse Autoencoders. They continue building on this work by modelling errors from these interpretability methods and testing techniques to reduce errors. Their research has garnered significant attention in the AI safety community and has led to significant advances in mechanistic interpretability work.

In 2019, the suffering of the world’s 440 billion shrimp was largely neglected. AWF's funding of Rethink Priorities’ cause prioritization work revealed this problem, then AWF grants launched the Shrimp Welfare Project (SWP) and other groups working on shrimp welfare. SWP improved 1.2 billion lives during their first two grant periods and secured commitments from 18 producers across the globe, helping 4 billion shrimp. Thanks to them and other advocacy groups AWF supported, nine retailers committed to humane stunning. The field transformed from nearly nothing to helping billions annually.

Effektiv Altruism Sverige (EA Sweden) held their largest-ever Nordic Group Organiser Retreat, convening organizers from 23 national, city, university, and field-building groups across six countries. The event included personalized support to help each group develop their Theory of Change, strategy, and organizational vision. Because of the low cost per attendee relative to similar events, we think this retreat is likely highly cost-effective.

With support from the Global Health And Development Fund, Innovations for Poverty Action conducted a randomized controlled trial of an intervention to distribute face masks and promote their use to reduce the transmission of SARS-CoV-2. This research found evidence that the intervention did increase mask-use and decreased symptomatic SARS-CoV-2 infections.
